WhiteListModel¶ ↑

Instead of using white_list_helper in every view just use it as model before_filter! This way you don’t have to escape/whitelist user-input data in every place they appear, just filter it on save.

Usage¶ ↑

class News < ActiveRecord::Base
  white_list  # Filter all string or text fields with standard filter set
end

class News < ActiveRecord::Base
  white_list :only => :description  # Filter description field with standard filter set
end

class News < ActiveRecord::Base
  white_list :except => [:title, :description], :profile => :mini # Filter everything except :title and :description with :mini profile
  white_list :only => :description, :method => :update, :profile => :web # Filter :description with :web profile and everything else except :title with :mini profile
end

Avalible parameters¶ ↑

:only => []          # Filter only included fields
:except => []        # Filter all string or text fields except included
:attributes => []    # Add specified attributes to allowed list
:bad_tags => []      # Add specified tags to completely trim
:protocols => []     # Add specified protocols to allowed list
:tags => []          # Add specified tags to allowed list
:profile => :default # Load specified profile. If no profile given then :default will be used. Avalible profiles :empty, :mini, :base, :web and :default
:method => :update   # You can use more than one set of parameters. Default method is :replace - when you use it then all previous options will be erased. But with :update method you can collect as many combinations as you want(see example above)

Profile will be used as template, and other options will be merged, so if you want options to be fully customized, use empty profile.
